+## Continuous Modernization
+
+This repository is configured for platform-managed continuous modernization.
+The platform can open PRs against `dev` at any time to:
+
+- Apply security patches and dependency updates
+- Enforce architecture conformance patterns
+- Promote environment configuration changes
+
+All platform PRs target `dev` first.
+Promotion to `main` requires approval via the Backstage deployment gate.
